SPECIFICATION forming part of Letters Patent N 0. 746,000, datedDecember 8, 1903.

Application filed April 24. 1903. Serial IDIO- l54,055. (No model.)

To all whont it rat/t7 concern:

3e it known that we, HENRY L. BRADLEY, residing at New Haven, andFREDERIC W. OTIS, residing at Orange, county of New Haven, State ofConnecticut, citizens of the United States, have invented a new anduseful Tinning-Machine, of which the following is a specification.

This invention relates to the tinning, so called-that is, the platingwith tinof small metallic articles.

Heretofore, so far as we are aware, articles have been tinned byhand-labor, no machines having been placed upon the market that wouldperform the operation successfully. In tinning articles by the presentmethod the operator uses a pair of tongs, with which he grips eachindividual article, plunges it into molten tin, and then shakes it twoor three times with great force in order to throw off the surplus tinand leave a smooth surface. The article is then laid on a revolvingtable and subjected to an air-blast to cool it and set the tin. Thismethod of tinning articles is slow wasteful, and necessarily expensive.As it is necessary to keep quite a large quantity of tin in a moltencondition, requiring the consumption of considerable fuel, it isdesirablethat the articles be handled as rap idly as possible. In doingthis the operators quickly become physically tired from shaking thearticles to remove Ihe surplus tin, with the result that a much largeramount of tin remains on the articles than is necessary or desirable,thus causing a constant waste of tin. Another serious difficulty is theconstant danger of the operator being burned by the. tin, as it is notprartirable to use any guard on the longs other than an ordinary glove.It. will he obvious, furthermore, that this hand operation of (inning isnecessarily relatively slow, no matter how inellectually the shakingoperation may be performed.

it is one of the objects of this invention to provide a tinning machinehaving a pair of jaws that will grip the art icle and hold it during thedippingoperation and will then Whirl it while gripped by the jaws, thusutilizing the principle of centrifugal force to remove the surplus tin.

It is a further object of the invention to provide a ti lining-machineso constructed that during the dipping operation the jaws will be whollydisconnected from the driving mechanism, thereby avoiding thepossibility of accident from the whirling motion being imparted to thejaws before they are withdrawn from the molten tin.

It is a further object of the invention to provide a tinningmachine soconstructed that the upward movement of the jaws after the dippingoperation shall set the machine in motion.

It is a further object of the invention to provide a tinning-machine soconstructed that when set in motion by the upward movement of the jawsas they are withdrawn from the molten tin the driving mechanism willimpart to the jawsa certain number of revolutions and will stop withthejaws in the starting position.

It is a further object of the invention to provide a tinning-machinehaving a receptacle under the jaws which will catch a.tinned article asit drops from the jaws when they are opened and will expel the tinnedarticle therefrom when the jaws are given a downward turn preparatory toplunging another article into the molten tin.

It is a further object of the invention to provide atinning-machinehaving jaws which hold an article while being dipped into molten tin andare then whirled to remove the surplus tin with a hood orguard Withinwhich the jaws revolve and which will catch all of the flying tin, thusavoiding waste of tin and also avoiding danger to the operator and toother persons and surrounding objects from the flying tin.

l Vith these and other objects in viewthe invention consists in certainconstructions and in certain parts, improvements, and combinations,whichwill be hereinafter described and then specifically pointed out in theclaims hereunto appended.

In the accompanying drawings, forming part of this specification, inwhich like charactors of reference indicate the same parts, Figure l isa plan view of the machine complete, the top of the hood being removedand the jaws in the gripping position; Fig. 2, a side elevation, thehood being in vertical section; Fig. 3, a detail sectional viewillustrating a portion of the clutch-releasing mechanism, the shoe beingin its normal or raised position, as in 2, and the bell-crank leverhaving commenced to swing downward as in withdrawing the shoe to releasethe sliding dog; 4, a similar view amplified, showing the position ofthe parts at the instant the shoe is released; Fig. 5, a detailsectional view showing the parts of the divided shaft in thedisconnected or broken position as during the dipping operation; Fig.(3, similar view showing said parts connected as during the whirlingoperation; Fig. 7, a detail sectional view showing the construction andoperation of the jaws which are in the open position, as when a tinnedarticle has been dropped and the jaws are ready to receive anotherarticle to be operated upon; and Fig. 8 is a detail sectional view onthe line indicated by 8 in Fig. 1, illustrating a form of brake whichmaybe used to check the rotation of the divided shaft.

denotes the bed,within which is a trough 2i for molten tin, the troughbeing covered by a suitably-shaped hood 22, having an opening 93.

23 denotes framework rigidly secured to the bed, which supports a stud24, on which a belt-pulley 25 and a gear-wheel 26 are mounted to turnindependently.

2'7 and 2S denote the two parts of a divided shaft which carries thearticle-holder, (designated as a whole by 29.) Part 27 of the shaft ismounted to turn in the framework and has a longitudinal bore in which arod 32 is adapted to reciprocate, the outer end of said rod projectingunder the rim of the belt-pulley,

indicated by dotted lines in Fig. 2.

3O denotes a pinion which meshes with gearwheel 26 and is secured topart 27 of the shaft, so as to drive the two-part shaft.

31 denotes a collar at the inner end of part 27.

lhe inner end of roc. 32 bears against the end of part 28, as clearlyshown in Figs. 5 and 6. Part 28 of the shaft is journaled in an arm 33,which is hinged, as at- 34, to a bracket 35, itself rigidly secured tothe bed. At the inner end of part 28 is a collar 36, which is rigidlysecured thereto.

37 (see Figs. 5 and 6) denotes a spring-controlled locking-pin,which issocketed in collar 31 and the forward end of which engages a recess 38in collar 36, thereby locking the two parts of the divided shafttogether, as clearly shown in Fig. 6, so that part 27 will drive part 28when said parts are in alinement.

It will be obvious from Fig. 2 that arm 33, carrying part 28 of theshaft, can only swing downward. Consequently the shaft can only breakdownward. It will be noted, furthermore, that when the shaft is broken,as in 5 and in dotted lines in 2, there is no connection whateverbetween the two parts of the shaft, so that even should the machine bestarted and rotary movement be communicated to part 27 it would have noeffect whatever upon part 28, and the operator would be perfectly safefrom any danger of having the jaws rotated while submerged in the moltentin. We furthermore insure that the shaft can only be broken when thejaws are swung downward into vertical-that is, the dipping-position.This is etfected by making recess 38 in collar 36 and the forward end oflocking-pin 37 straight upon the lower side and making both of saidparts upon the upper side an arc-shaped curve, of which pivotal point 34is the center, said curve upon the locking-pin being indicated by 94.This construction permits the shaft to break readily when the parts arein the position shown in Fig. 5 and indicated in dotted lines in Fig. 2,but in no other position, as the pin will bind in the recess and lockthe parts of the shaft in alineinent, except when locking-pin 37 and thecorresponding recess are in a predetermined position--as, for example,when collars 31 and are in such a position as to place said locking-pinand recess directly under sliding rod 32, as in Fig. 5. This is a matterof importance, as it renders it impossible for the shaft to break eitherby accident or otherwise except when the shaft is stationary and in oneposition onlythat is, with the jaws in the dipping position.

39 (see dotted lines, Fig. 2) denotes a springactuated pin socketed inbracket and engaging a knuckle 40 on arm 6., the hinge member of saidarm-in such a manner as to throw part 27 of the shaft upward to thenormal or operative position, as in Figs. 1, 2, and 6, after said partshave been separated, as in Fig. 5, or, as we term it for convenience,the shaft has been broken.

The hub 41 of article-holder 29 is rigidly secured to the outer end ofpart 28 of the divided shaft. The construction of the holder will bereadily understood from Fig. 7, which seein connection with Fig. 1. 42denotes the jaws, which are pivoted to a cross-piece 43, carried by arod 44, which passes through a carrier 45, itself rigidly secured in hub41. The forward end of the carrie is beveled, as at 46, and is engagedby the rear ends of the jaws. A spring 47 within the carrier, bearingagainst shoulders on the carrier and on the rod, acts to retract the rodand, through the engagement of the rear ends of the jaws with thebeveled end of the carrier, to force the jaws to the closed or grippingposition, as in Fig. 1. At the inner end of rod 44 is a head 48, whichlies in a socket 49 at the rear end of the holder. A handpiece 50,pivoted in the socket, is provided with a boss or projection 51, adaptedto engage head 48 when the handle is oscillated, as in Fig. 7, to forcethe rod and jaws forward against the power of spring 47. Springs 52,which are secured to the holder, bear against the rear ends of the jawsand throw them to the open or releasing position when the rod is forcedforward by engagement of the boss on the handpiece in connection withFigs. 2,

with head 48 when the handpiece is oscillated, as in Fig. 7, the forwardmovement of the rod, cross-piece, and jaws causing the rear ends of thejaws to ride down the beveled end so of the carrier. The instant thehandpiece is moved back to its normal position, as in 1, spring 47 willmove the rod, crosspiece, and jaws backward, causing the rear ends ofthe jaws to ride up the beveled end of the carrier and throw theirforward ends to the gripping position against the power of springs 52,as in Fig. 1. The handpiece is shown as provided with a lug 53, which,when the handpiece is thrown to the releasing position, as in Fig. 7,passes into a slot 55 in the rear end of the holder, serving as a guide,and with a lug 54, which when the handpiece is at the gripping position,as in Fig. 1, engages the rear end of the holder, serving as a stop.

The machine is driven by means of a belt (not shown) passing over thebelt-pulley, which is connected by means of clutch mechanism withgear-wheel 26, which in turn meshes with pinion 30. The gear-wheel isprovided with a hub 56 having a groove 57.

58 denotes a sliding clutch-dog carried by the hub, which is actuated bya spring 91 and is adapted to engage a socket 59 in the hub of thebelt-pulley. (See dotted lines, Fig. 1.) This clutch-dog is providedwith a lug 60, which is adapted to engage an incline 61 on a shoe 62,which lies in groove 57 in the hub of the gear-wheel. (See dotted lines,Fig. 1, 3, and 4.) The shoe is provided with a shank 68, which extendsdownward into asocket 61 in the framework and is provided with a recess65, whose lower wall is adapted to be engaged by a dog 66, pivoted in arecess 67 in a bell-crank lever 68, itself pivoted to the framework, asat 92, and lying partly under the rim of the beltwheel. (See Fig. 2 inconnection with Fig. 1.) A spring 69, lying in the base of socket U1,acts to throw the shoe upward to the engaging position, as in 2 and 3,and a spring 90 (see Fig. t) acts to throw the bellcrank lever and dogto the raised or engaging position when part 27 of the divided shaft ismoved outward, as will be more fully explained.

7O denotes a lug seated in the framework and passing through an opening71, which leads into recess 67 in the end of the bellcrank lever, thefunction of which is to engage the rear end of dog 66, that is back ofthe pivotal point, and tilt said dog when the bell-crankleveris swungdownward,as clearly shown in Fig. 4, and draw down the shoe to releasethe sliding clutch-dog, as will be more fully explained.

In order to stop the rotation of the divided shaft the instant thepredetermined number of revolutions have been completed, leaving thejaws in the starting position, we provide a suitable brake, whichoperates in connection with gear-wheel 26. In the present instance wehave shown a collar 72, having a boss 73. (See Fig. 8.) The collar isrigidly secured to the gear-wheel and turns with it on stud 24:. Asuitable pad 74, carried by a housing 75 upon the framework, is engagedby the boss on collar 72 at the end of each rotation of the collar, asclearly shown in Fig. 8. The pressure of the pad upon the boss may beregulated by means of a setscrew 76 in the housing. In the side ofgearwheel 26 we provide a recess 77, which is adapted to be engaged by ahook 78 on a lever 79, which is pivoted to the framework, as at 80. Theengagement of the hook with the recess takes place an inst-ant after theenpinion may be to each other as three to one or four to one, it beingsimply required to give to the tongs a sufficient number of revolutionsto throw the surplus tin from the article they are holding:

81 denotes a link, one end of which is pivoted to lever 79, the other toa lever 82, which is itself pivoted, as at 83, to a bracket 84, whichextends outward from the bed.

85 denotes a receptacle hinged, as at 86, to lever 82 and normallystanding upright directly under the jaws. A spring 87 (shown asconnected to lever 79 and to the bed) acts to return lever 79, the link,lever 82, and the receptacle to their normal positions and retain themthere. The receptacle is made of suitable shape and size to receive andretain temporarily an article dropped into it from the jaws. \Vhen lever82 is thrown to the position shown in dotted lines in Fig. 1, as will bemore full; explained, the receptacle which is hinged on the side in thedirection of movement of the lever will be thrown by centrifugal forcefrom the upright to a horizontal position and will expel therefrom thearticle that has been dropped into it from the jaws, the horizontalposition of the receptacle being indicated by dotted lines in Fig. 1. Onthe return movement of lever 82, which takes place an instant later, thelever strikes a pin 88, projecting upward from link 81,

which stops the movement of the lever, and

centrifugal force causes the receptacle to resume its upright positiondirectly under the jaws, as clearly shown in Figs. 1 and 2.

The operation of the machine is as follows: Belt-pulley 25 is always inmotion when the machine is in use. The other parts of the machine arestationary, except when in actual use. The normal position of the jawsis horizontal, as in full lines in Figs. 1 and 2. Suppose the machine tohave been in use and a tinned article to be held bythe jaws. Theoperator first moves handpiece 50 from the Ito position shown in Fig. 1to the position shown in Fig. 7. This movement through the engagement ofboss 51 with head 48 on rod 44, which carries the jaws, moves said jawsforward, causing the rear ends thereof to ride down the beveled end 46of carrier 45 and permitting springs 52 to throw the jaws to the openposition, as in Fig. 7. This releases the article held by thejaws, whichdrops into the receptacle. The operator then places another article tobe tinned between the jaws and moves the handpiece back to the positionshown in Fig. 1. Spring 47 moves rod 44, carrying the jaws backward, andthe rear ends of the jaws ride up bevel 46 at the forward end of thecarrier, which throws the jaws to the closing position, as in Fig. 1,against the power of springs 52, thus gripping the article firmly, oneof thejaws being of course provided with as small a contactpoint aspossible, as at 89, but which is so shaped as to grip and hold thearticle firmly. The operator next still gripping the handpiece swings itupward, which swings the jaws downward into the vertical position. Henext, still holding the handpiece, swings the jaws inward and downwardagainst the power of spring-actuated pin 39, as indicated by dottedlines in Fig. 2, and dips the article held by the jaws in the molten tinin the trough. When the jaws are swung downward to dip the article, arm33, which carries part 26 of the divided shaft, turns on its hinge, asindicated in dotted lines, the position of the parts of the shaft beingclearly shown in Fig. 5. When the inner end of part- 28 is swungdownward and outward away from collar 31, spring 90 will act to raisebell-crank lever 68, the lower arm of which will press sliding rod 32inward. (See Fig. 5 in connection with Fig. 4.) It has already beenexplained that at the end of each whirling operation the rotation ofgear-wheel 36, the divided shaft, and the jaws will be stopped throughtheengagement of boss 73 on collar '72,carried by the gear-wheel withpad 74, after which book 78 on lever 79 engages recess 77 in the side ofthe gear-wheel and locks the gear-wheel, shaft, and jaws in the normalor starting position. It should be understood that the engagement ofhook 78 with the recess in the gear-wheel although positive is a lightengagement, so that the first movement of the jaws and the dividedshaft-that is, the oscillation of the shaft which lowers the jaws fromthe horizontal to the vertical positionwill through the engagement ofpinion 30 with the gear-wheel turn the latter slightly and throw thehook out of the recess against the power of spring 87, as clearlyindicated by dotted lines in Fig. 1, which throws the receptacle andexpels an article therefrom, as already explained. This oscillation ofthe shaft carries the gear-wheel forward in the direction of the arrowin Fig. 1 far enough to carry the recess beyond the hook, which willrest against the side of the gear-wheel ready to engage again at thecompletion of the next revolution. Before the breaking of the shaftthatis, the downward movement of part 28 to dip an articlebell-crank lever68 was in the position shown in Fig. 4, but'shoe 62 was in the positionshown in Figs. 2 and 3that is, held at its extreme upward position ingroove 57 by means of spring 69. The extreme nptilted position of thebell-cranklever is not shown in the drawings, the position shown in Fig.3 being after said lever has commenced to swing downward, and pivoteddog 66 through its engagement with recess 65 is about to draw the shoedownward, as will presently be fully explained. It will be obvious thatwith the bell-crank lever in the uptilted position and the inner end ofsliding rod 32 in the position shown in Fig. 5 the re turn of arm 33,part 28 of the shaft, and the jaws from the position shown in dottedlines in Fig. 2 to a position in which the parts of the shaft will be inalineinent with each other, as in Figs. 2 and 6, the jaws, however,still being downward will force sliding rod 32 outward, as in Fig. 4,and will throw the bellcrauk lever from the uptilted position to thedowntilted position, as in Fig. 4, against the power of spring 90. Asthe bell-crank lever commences to swing downward, pivoted dog 66 willengage recess 65 in the shank of the shoe and will tilt said dog untilthe rear end thereof engages the bottom of recess 67, in which it ispivoted, as in Fig. 3, when continued downward movement of thebell-crank lever will draw the shoe downward from the position shown inFigs. 2 and 3 and in dotted lines in Fig. 4 to the position shown infull lines in Fig. 4. As the downward movement of the bell-crank levercontinues, the rear end of dog 66 will engage lug 70, which projectsupwardinto recess 67 through opening 71 and will tilt the rear end ofsaid dog, as in Fig. 4, sufficiently to swing the forward end thereofout of recess 65 in the shank of the shoe. The instant the shoe isreleased by the passing of the forward end of the dog out of the recessspring 69 will again throw the sho to the raised position, as in Figs. 2and 3. The bell-crank lever, however, will remain in the position shownin Fig. 4 untilthe breaking of the shaft, as in Fig. 5, again permitsspring 90 to uptilt the bell-crank lever and force the sliding rodinward. l'he lower arm of the lever remains constantly in contact withthe sliding rod, the outer end of which is shown as rounded, so as toreduce friction to the minimum.

The inoperativethatis, the disengaging position of sliding clutch-dog 58is clearly shown in Fig. 2, in which position it, is retained by theshoe until the latter is drawn downward, explained. WVhen the jaws, arm33, and part 28 of the divided shaft are swung downward, as in dottedlines in Fig. 2, said part 28 of the divided shaft moves outward towardthe right, (see Fig. 5,) which leaves spring 90 free to uptilt thebell-crank IIO lever and move the sliding rod toward the right from theposition shown in Figs. 4 and 6 to the position shown in Fig. 5, theinner end of the sliding rod following part 28 of the shaft andremaining in contact therewith. After the dipping operation the operatormay swing part 28 of the divided shaft upward to the horizontal positionor he may let go of the handpiece and leave this upward movement of thearm, jaws, and part 28 to be produced by spring-actuated pin 39. It willbe obvious from Figs. 5 and 6 that this upward movement of part 28 ofthe divided shaft will force the sliding rod toward the left, as in Fig.4, the effect of which will be to tilt the bellcrank lever downward andcause pivoted dog 66 through its engagement with recess in the shank ofthe shoe to draw the shoe downward, which releases sliding clutch-dog 58and permits spring 91 to throw it forward into engagement with socket 59in the belt-pulley. The downward movement of the bell-crank levercontinues until pivoted dog 66 through the engagement of the rear endthereof with lug 70 is tilted sufficiently to swing the forward end ofthe dog out of recess 65, when spring 69 will instantly throw the shoeupward again to its normal position, as in Figs. 2 and 3, thebell-cranklever, however, remaining in the position shown in Fig. 4until it is again tilted upward by the breaking of the shaft, as alreadyexplained. The instant the sliding clutch-dog engages the recess in thebelt-pulley motion is communicated to gearwheel 26, the pinion, shaft,and jaws, and the whirling operation takes place. It should be noted,however, that injury to the operator or to the machine by prematurerotation of the divided shaft and jaws is rendered practicallyimpossible, as it is the upward movement of arm 33, part 28 of theshaft, and the jaws that causes the sliding rod to produce the downwardtilt of the bell-crank lever, which in turn draws the shoe downward andreleases the sliding clutch-dog, it being noted, furthermore, that theslight rotary movement imparted to the gear-wheel by the oscillation ofthe jaws at the time hook 78 is disengaged from the recess in the sideof the gear-wheel and the article last tinned is expelled from thereceptacle, stops the instant the jaws reach their downward position andis a hand movement only, the gear-wheel not being connected with thebelt-pulley until the shoe is drawn downward by an upward movement ofpart 28 of the shaft after the shaft has been broken. As already fullyexplained, the whirling operation is produced by a plurality ofrevolutions of pinion 30, which are produced by a single revolution ofthe gearwheel. As the gear-wheel approaches the end of a revolution lug60 on the sliding clutch-dog comes into engagement with incline 61 onthe shoe, (see dotted lines, Fig. 1,) the lug riding up the incline andwithdrawing the sliding clutch-dog from socket 59 in the belt-pulley.The instant this disengagement is effected boss 78 on collar 72, movingwith or forming part of the gear-wheel, engages pad 74, which stops therotation of the gear-wheel, pinion, divided shaft, and jaws. An instantlater the gear-wheel is looked through the engagement of hook 78 withthe recess in the side of the gear-wheel. This completes the operationof tinning an article. The operator then opens the jaws, as in Fig. 7,which releases the tinned article, permitting it to drop into thereceptacle, then places another article to be tinned between the jawsand closes the jaws by moving the handpiece backto the position shown inFig. 1, then oscillates the divided shaft to carry the jaws downward,and then breaks the shaft, swinging part 28 and the jaws downward, asbefore, to dip the article in molten tinin the trough, the upwardmovement of part 28 of the shaft producing the downward movement of theshoe and causing the release of the clutch-dog and connecting thegear-wheel with the belt-pulley, as before.
